In addition, this selective weed killer will delay weed regrowth as much as possible without harming your lawn.
You'll see results in a few days as the weeds begin to fade and turn brown. But it will take about 2 weeks to completely kill the affected plants. Cetaflor Weedex is suitable for lawns and does not harm grass. There are exceptions, so be careful with use and dosage.

See priceThis 10 kg bag of NPK fertilizer can treat up to 300 m² of lawn while acting on moss and weeds. Versando is especially recommended for sports fields and special lawns. It offers an immediate action to green up and densify the lawn. To do this, spread 30 g/m² of product 4 times a year (in March-April, June, August and September).
Note that the spreading should be done 1 to 2 days after mowing. So, don't expect a herbicide fertilizer to do everything in a few days. It will probably take 2 weeks to see a decrease in moss and weeds. After that, the color of the grass and its growth can only improve.

Emergence refers to the stage of weed growth at which you should apply the weed killer.
Selectivity is the ability of a weed killer to kill weeds while leaving surrounding plants unharmed.
Translocation describes the movement of the product into a weed once it is absorbed by the plant's leaves, stems, or roots.
Persistence tells you how long after application a weed killer remains in the soil and can act
.
The choice of a selective weed killer should also depend on the area to be treated. If it is quite large, the ideal is to choose a concentrated weed killer to dilute. On the other hand, for small surfaces, ready-to-use weedkillers are the most suitable.
Since selective weed killer is a chemical product, it is important to know how to use it properly. It is therefore necessary to read carefully the instructions provided by the manufacturers before anything else. It is imperative to respect them for a good application. First, you must evaluate the size of the surface to be treated.
If you have a large area, you must use a more concentrated solution. The use of a specific weed killer is therefore strongly recommended. Indeed, on a surface larger than 100 m², the ideal is to apply a selective weed killer in granules.
Now you can proceed to mix the water and the product. To do this, you can use a watering can or do it directly in the tank of your sprayer. Then, spray your lawn and for a better efficiency, make sure that you have spread it all over the lawn.
For a small area, using a ready-to-use solution with a simple watering can can be enough for a complete watering of your garden. In addition, it allows you to apply more precisely on the plants to be removed.
As for the right season to apply the weed killer and get the best results, it is recommended to do it in early spring, in March or April, but it depends on the region. In addition, it is advisable to apply it when the outside temperature is between 15° and 22°C.
Apart from that, you should mow the lawn before applying the weed killer. In addition, you must water your lawn the day before application. Finally, in order to keep your lawn in good condition as long as possible, and especially for an effective elimination of weeds, the ideal is to perform this operation once or twice a year.
Already, the selective weed killer is a sub-type of weed killer. Depending on the form and presentation, there are 3 types of selective weed killers.
This is the most common form. This type of selective weed killer offers more flexibility in its application. Because this type of weed killer is highly concentrated, it must be diluted and applied with a watering can or sprayer. Ideal for large areas, concentrated liquid weed killer can be used to treat the lawn in the spring or fall. It is also an excellent choice if your lawn has a lot of weeds.
Most concentrated weed killers can only be applied once a year. However, there are different active ingredients, which means you can spray your lawn twice a year, each time with a different brand.
These types of selective weed killer sprays do not need to be mixed. They are ready to use and come in a spray bottle. They are great for sparingly eliminating weeds. This makes them ideal if there are few weeds to remove in your lawn.
Plus, since you don't usually apply them to your entire lawn, you can use them whenever you need them.
There
are very few granular weed killers on the market. They are usually incorporated into other products such as in fertilizers and spray weed killers, but rarely as a stand-alone weed killer.
If you don't have many weeds in your lawn and would rather invest in plant growth products than apply a separate fertilizer and weed killer, use one. However, if your lawn is already overrun with weeds, opt for a concentrated weed killer.
As the name implies, selective weed killers only kill certain species. They generally target broadleaf weeds. Furthermore, they are suitable for large lawns and usually do not cause damage to the grass. And one of the biggest advantages of this type of weed killer is that one application can last an entire season.
Some selective herbicides can be harmful to a certain type of grass (these are usually the products targeted at sedges and rushes), so check the label carefully before purchasing a product. On the other hand, selective weed killers may take time to work, but are less harmful.
Multipurpose weed killer is also called broad spectrum weed killer. It is very effective in killing plants. But this effectiveness is double-edged. If applied incorrectly, broad-spectrum weed killer can kill not only the weeds but also the grass or flowers you think you are protecting!
Indeed, this type of weed killer kills most of the plants it comes into contact with. They are therefore very harmful. Several precautions should be taken before applying them, to avoid contaminating other areas of your garden.
Selective weed killers are particularly effective on lawns because they kill broadleaf weeds but do not affect other plants. Use non-selective weed killers on large areas of the garden that need to be cleared, as well as driveways and paths.
Still hesitating to use a selective weed killer? Here are the reasons why this product will be beneficial to your lawn and more generally to your garden.
Effective weed control
Proper maintenance of your lawn and garden allows plants to grow properly and blocks the development of weeds. Selective weed killers only kill a specific type of weed or plant, while non-selective weed killers kill all plants they touch.
Ease of use
Manual weed control requires digging and pulling by hand. This can be time-consuming and can lead to soreness. Also, some weeds have long roots that require additional digging to remove the entire root. A weed killer is easier to apply because you simply spray it on the plant. It takes over at that point to kill the unwanted plant.
Increases the harvest
By removing weeds that compete for water, sunlight and nutrients, weed killers increase crop yields, resulting in lower prices, greater profits and fewer food shortages.
Fast and effective
One of the main reasons people turn to weed killers is that they provide a quick solution. Some products can kill weeds in less than a day, while others can take weeks or more. It should not take more than a month for the weeds to die completely.
Less harmful
Selective weed killers are less harmful than non-selective weed killers. In addition, they can be sprayed sparingly on weeds only.
In our opinion, the best brands of selective weed killers for lawns in 2022 are :
Bayer is a German company founded in 1863. It specializes in life sciences and has 150 years of experience. The brand's Crop Science division provides us with cutting-edge products in crop protection, particularly in the field of herbicides.
It is renowned for having always sought to develop a know-how and an approach to natural gardening. It therefore offers products that respect the environment and are in phase with nature, whether in terms of fertilizers or weed control.
Celaflor Naturen (since 2008) or Naturen is a brand that belongs to the company La Pause Jardin (Liebe deinen Garten). It offers products that are 100% natural and therefore perfectly compatible with the environment without sacrificing effectiveness.
The Preen brand is owned by the Lebanon Seaboard Corporation and has over half a century of experience. Its products are reliable and environmentally friendly and are the easiest solution to help you weed your garden or lawn.
Scotts (or Scotts Miracle-Gro Company) is an American multinational company founded in 1868. It is best known for the manufacture and distribution of consumer lawn and garden products, including selective weed killers. Its products are reliable and respect the environment.
The diagram below will help you to get an idea of the typical prices for each price range (entry-level, mid-range and high-end).
However, more expensive does not necessarily mean better.
We therefore advise you to always consult our ranking before deciding, rather than blindly relying on price ranges.
Avoid spraying in extremely hot weather
Temperatures above 85 degrees will amplify the stress on the grass and cause damage. It is best to wait for temperatures below 80 degrees.
Do not apply any chemicals to the young grass.
They do
not have the same chemical resistance as mature grass. It is advisable to wait at least three months to spray exposed new grass.
Do not mow the lawn for 2 to 3 days before spraying.
Weed killers must be absorbed by weed leaves, and short weeds drink less chemical. Wait at least a few days after mowing to spray and do not mow for several days after spraying, which can allow more chemicals to get down to the root.
Cut the most stubborn weeds
If
your garden is already overgrown with weeds, it is recommended that you cut them back and wait for new leaves to appear. This will make it easier for the weed killer to penetrate the plant, killing it faster and more effectively.
Water your plants, not your herbs
If
you really want to keep weeds from growing, don't water them! Placing a soaker hose under your mulch and watering only your plants will prevent water from seeping into the weeds, stunting their growth.
The best selective weed killer depends on your needs and budget. Read our buying guide for the best products available.
Use only during the growing season when growth is good normally 2 days after mowing and at least 3 days before the next cut.
In calm and dry weather, avoid heat and sun
You can mix the selective weed killer with the soluble lawn fertilizer to do two jobs in one. If you use them separately, apply the soluble fertilizer first and the weed killer about a week later.
Virtually any weed killer containing chemicals is dangerous to animals and children.
